Specification of Letters Patent.

Patented June 12, 1906'.

.To all whomit may concern: I

Be it known that I, MAURICE -GASTON OLIVIER, engineer, acitizen of theFrench Republic, residing at Paris, France, have invented certain newanduseful ments in Self-Fixing Protective Coverings for Bottles, Jars, orother Vessels, of which the following is a specification.

Bottles containin liquid or other preparations are usually cIosed with asto per or cork and also generally provided wit a rotective covering,which may be of leat or, skin, metal, pa er, or other suitable material,for the fixing 0 which certain manual or mechanical 0' erations arenecessary.

I have f dund that a film of cellulose, such as can be obtained byprecepitation from the solution of cellulose known as viscose, can bepre ared into suitable shape or form, and this 'w en laced upon. thebottle, jar, or

other vesse shrinks possible contact, forming a perfectly tight oint.Thus for an ordinary stop red bottle used to put 11 pharmaceuticaprepara- (1 these coverings of cellulose hydrate bv coatin the roundedand closed ends of cylindrica and setting the solution by any of thewellknown means. The shaped films are detached, purified and washed, andpreservedin contact with water in the hydrate condition. These films aremade slightly larger than the neck of the bottle or vessel to becovered, so that they slip on quite easily- The length is also adjustedaccording to re-v quirements. The film when placed on the bottle orvessel shrinks ontaneously and readily accommodates itse f to the shapeof the vessel. 7 Solutions oficellulose other than viscose havingsimilar properties may. of

course be used.

The essence of my invention consists in the fact that the cellulosefilm.in its-hydrated for'm shrinks ve considerably as itpartsautomaticallywit its moisture, that during its spontaneous shrinkage it.takes the form of, and molds itself upon, the stopper, or'cork on whichit is placed, making a perfectly.

Improvey loss of moisture and( attaches itself spontaneously at all.points of tubes with viscose I. tight joint, and that in the air-drystate it possesses the tensile properties necessary to withstand thestrains wh1ch are'set u .by the shrinkage. The joint above referre to isso perfect that there is not the slightest leakage with fatty matters orthe most mobile liquid, like petroleum. I

In the drawing the figure illustrates in broken elevation a bottlehaving my improved covering applied thereto.

In said drawing, 1 indicates the body of the bottle; 2, the neckthereof; 3, the cork inserted in said-neck, and 4 my improved coating orcovering a plied about the neck of thebottle and over t e top of saidcork.

. claim I 1 A self-fixing protective covering for bottles, jars, orother vessels, comprising an apropriately-shaped film or coveringof'cellulbse hydrate adapted, when placedupon the bottle or othervessel, to-shrink by loss of moisture and so attach itself firmly at allointsof possible contact, substantially as hereinbefore described.

2. The method of producing a self-fixing I protective covering forbottles, jars or other vessels, which consists in forming a body ofcellulose hydrate into the shapeof the covering desired, but slightlylarger than the neck .of the bottle or vessel to be covered, so thatitself firmly slightly larger than the neck of the bottle or vessel tobe covered.

In testimony whereof I have herelinto set my hand in presence of twosubscribing witnesses.
